本文提出以5-Br-PADAP双波长K系数法同时测定钻镍的新方法。该法灵敏度高,选择性好,用于若干组成复杂样品的分析,在CO:Ni=20:1或1:15范围均可获得满意结果。
This paper presents a new method for the simultaneous determination of nickel by 5-Br-PADAP dual-wavelength K-factor method. The method has high sensitivity and good selectivity and is used for the analysis of several complex samples. Satisfactory results are obtained in the range of CO: Ni = 20: 1 or 1:15.
